A synovial joint, also known as diarthrosis, joins bones or cartilage with a fibrous joint capsule that is continuous with the periosteum of the joined bones, constitutes the outer boundary of a synovial cavity, and surrounds the bones' articulating surfaces. This joint unites long bones and permits free bone movement and greater mobility. [1] .

Describe the characteristic features for synovial joints and give examples. Describe the structural features and functional properties of a synovial joint; Discuss the function of additional structures associated with synovial joints; Compare the six types of synovial joints

2023年9月18日 · Synovitis happens when a synovial membrane or the fluid inside it is damaged or irritated. The affected synovial membrane swells up, thickens and causes pain and other symptoms inside your joints. Visit a healthcare provider if you’re experiencing new joint pain or other symptoms, like stiffness or trouble moving a joint.

Now it is possible, using artificial synovial fluid agents such as hyaluronic acid. Apatite crystals can be demonstrated in the synovial aspirate. The fluid contains hyaluronic acid secreted by …

Synovial joints are the most common type of joint in the body (see image 1). These joints are termed diarthroses, meaning they are freely mobile. A key structural characteristic for a synovial joint that is not seen at fibrous or cartilaginous joints is the presence of a joint cavity.

2024年9月7日 · A synovial joint is characterised by the presence of a fluid-filled joint cavity contained within a fibrous capsule. It is the most common type of joint found in the human body, and contains several structures which are not seen in fibrous or cartilaginous joints.

滑膜关节（synovial joint）常简称关节，由两块或两块以上的骨构成，相对骨面之间有间隙，仅借其周围的纤维结缔组织膜相连。 滑膜关节是骨连结的主要形式，具有很大的活动性。

Your synovial membranes protect the joints they surround. They form what’s called a synovial capsule around your joints. They work with your cartilage, tendons and ligaments to reduce friction between the bones in your joints — especially when you’re moving them.

Synovial joints allow for smooth movements between the adjacent bones. The joint is surrounded by an articular capsule that defines a joint cavity filled with synovial fluid. The articulating surfaces of the bones are covered by a thin layer of articular cartilage.

Synovial joints allow for movement. Where the bones meet to form a synovial joint, the bones' surfaces are covered with a thin layer of strong, smooth articular cartilage. A very thin layer of slippery, viscous joint fluid, called synovial fluid, separates and lubricates the two cartilage-covered bone surfaces.
